Sadie Sink Joining Avengers: Secret Wars After Spider-Man: Brand New Day

by

Sadie Sink is making a fast jump from Spider-Man to the Avengers.

Okay, so according to Deadline, this actress is going to be in Avengers: Secret Wars! They’re filming that one in London sometime in late 2026, and it comes after she’s already starring in the new Spider-Man movie, Brand New Day, which hits theaters on July 31st. Pretty exciting stuff if you ask me!

Details about Sadie Sink’s part in the upcoming Spider-Man movie are still secret. However, Deadline reports she’s also committed to a large-scale Marvel film that will begin filming after the Spider-Man movie is released. Sources say she’ll be working on Brand New Day until December.

The new Spider-Man movie, Spider-Man: Brand New Day, is set to be released on July 31st. There’s been a lot of talk about what role actress Sink will play in the film, but I don’t have any information about that. However, I do know she’s confirmed to be in the next Avengers movie, which will be filmed in London later in 2026.

How This Fits Into Marvel’s Plans

Having Valentina Romanoff recruit Yelena Belova immediately after the events of Black Widow suggests Marvel is building her up as a key player for future stories.

People are speculating about who the new character could be, with theories ranging from a mutant to someone from another universe, but so far, nothing has been officially revealed.

Marvel Studios only features actors in both Spider-Man movies and Avengers films if their character plays a significant, ongoing role that links the two storylines.

Still No Word on Her Character

Both Marvel and Sony are keeping Sink’s role a secret. This mystery surrounding the upcoming Brand New Day project has sparked a lot of speculation, particularly because she’s rumored to be joining an Avengers film shortly after.

Her future role in the Marvel Cinematic Universe is still a major mystery as they plan their upcoming stories.

A Big Move for Sink and the MCU

Sadie Sink gained widespread recognition from her role in Stranger Things, and now she’s poised to become a leading figure in the Marvel Cinematic Universe. With Brand New Day scheduled for release in 2026 and the next Avengers film starting production soon after, fans won’t have to wait long to see how her character will be integrated into the bigger Marvel story.
